Hi Joe,
You don't mention any other symptoms like a painless swollen gland, difficulty swallowing etc. so it could be any number of things that aren't cancer.
A biopsy is the most definitive way to diagnose OC. It sounds like your oral surgeon is erring on the side of caution and that's a good thing. Hopefully it's nothing and life can go on for you and your family.
Positive thoughts and prayers
